2.6.2 Digital I/O

Digital inputs can be set to provide many indicator functions, including all keypad functions except MENU. Digital
inputs are active (on) with low voltage (0 VDC), inactive (off) at 5 VDC. Use the DIGIO menu to configure the
digital inputs.
Digital outputs are typically used to control relays that drive other equipment. Outputs are designed to sink, rather
than source, switching current. Each output is a normally open collector circuit, capable of sinking 250 mA when
active. Digital outputs are active when low or at 0 VDC, with reference to the 5 VDC supply.
Use the DIO menu to set the function of the DIO pins to OUTPUT, them use the SETPTS menu to configure the
digital outputs.
Table 2-4 shows the pin assignments for connector J6.
